Scientists have solved a major problem with the current standard model of cosmology identified by combining results from the Planck spacecraft and measurements of gravitational lensing in order to deduce the mass of ghostly sub-atomic particles called neutrinos.
In this paper, Professor Battye and co-author Dr Adam Moss, from the University of Nottingham, have combined the data from Planck with gravitational lensing observations in which images of galaxies are warped by the curvature of space-time. They conclude that the current discrepancies can be resolved if massive neutrinos are included in the standard cosmological model. They estimate that the sum of masses of neutrinos is 0.320 +/- 0.081 eV (assuming active neutrinos with three flavours).
Dr Moss said: “If this result is borne out by further analysis, it not only adds significantly to our understanding of the sub-atomic world studied by particle physicists, but it would also be an important extension to the standard model of cosmology which has been developed over the last decade.”
If the standard model of physics turns out to work over the long run, that’s bad news for multiverses, right? They were supposed to fix the mess that the standard model is supposedly in, but by all accounts, much less radical and arbitrary fixes of current problems are quite sufficient.
We aren’t supposed to say this, but the main rap against the standard model’s Big Bang has always been that it seemed to support theism, and worse luck, the Darn Thing just won’t get itself disproven or declared irrelevant, and go away.
By the way, speaking of “Multiverse advocate defends in SciAm against charges that his claims are ‘unscientific nonsense’”: Has Max Tegmark been attacked for receiving Templeton funding? The way Martin Rees was attacked for getting the Templeton prize? If not, funny the silence …
